	NSLS-II is a state-of-the-art third-generation light source under construction at BNL. As many facilities worldwide, NSLS II uses the EPICS control system to monitor and control all accelerator hardware. CSS is used for simple tasks such as monitoring, display, setting of PVs and browsing the historical data. For more complex accelerator physics applications, a collection of scripts are mainly written in Python. The controls group developed the services, such as channel finder, machine snapshot, data archiving, twiss server, unit conversion etc. This paper will present the tools that we have been using for commissioning.

	Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-AC02-98CH10886 with the U.S. Department of Energy. A new superconducting solenoid magnet was installed in the yellow ring of RHIC before Run 13 as part of the e-lens project. The second solenoid superconducting magnet will be installed in RHIC after Run 13 is over. There are 6 power supplies required for the solenoid, fringe and anti-fringe coils for both magnets. Commercial off the shelf unipolar power supplies are used to power the solenoid, fringe and anti-fringe coils. There are 24 corrector power supplies required for both magnets. Custom built 50A bipolar power supplies are used to power the correctors. Quench protection and quench detection have also been installed in this power supply system. In addition, 4 new phase shift power supplies have been installed in RHIC which are needed for the new e-lens system. These phase shift power supplies have been installed across the yellow focusing and defocusing arcs as well as the blue focusing and defocusing arcs from sector 8 to sector 10. Power Supply technology, control system, connections, the quench detection/protection system, and status will be presented.
